The invention relates to an automatic driving vehicle driving intention roadside projection method and device based on vehicle and road cloud, and the method comprises the steps: collecting all current target traffic participants in a coverage range of a target intelligent roadside unit in real time; information such as the real-time state of each autonomous vehicle, real-time information of other target traffic participants and predicted track points in a preset time period are acquired, and risk analysis is performed on all the target traffic participants according to the information such as the real-time state so as to determine traffic participants to be pre-warned and corresponding projection information; environment information of the current road is collected, each target roadside projection unit is determined according to the environment information, and sub-projection information corresponding to each roadside projection unit is generated based on the projection information, so that the sub-projection information is projected to the corresponding projection surface. Therefore, the problems that information completeness of an existing vehicle and road cloud interaction technology is insufficient, pedestrians need to carry terminal equipment, popularization and application are not facilitated, and the actual use effect is greatly affected are solved.
本申请涉及一种基于车路云的自动驾驶车辆行驶意图路侧投影方法及装置,其中,方法包括:实时采集目标智能路侧单元覆盖范围内的当前所有目标交通参与者;获取每个自动驾驶车辆的实时状态等信息以及其他目标交通参与者的实时信息和预设时间段的预测轨迹点,并根据实时状态等信息对所有目标交通参与者进行风险分析,以确定待预警交通参与者和对应的投影信息;采集当前道路的环境信息,并根据环境信息确定每个目标路侧投影单元,且基于投影信息,生成每个路侧投影单元对应的子投影信息,以将子投影信息投影至对应的投影面。由此,解决了现有车路云交互技术的信息完备性不足,且需行人携带终端设备,不利于推广应用,极大影响实际使用效果等问题。
